Deck 22: Position Tolerance - Special Applications

Question 1

A functional gage can be used to verify the projected tolerance zone.

Answer 1

True

Question 2

Explain a projected tolerance zone.

Answer 2

A projected tolerance zone is a tolerance zone that is moved outside of the feature. The height that the tolerance zone is projected must also be specified. A projected tolerance zone exists wherever the projected tolerance zone modifier is specified in a feature control frame.

Question 3

What are the three primary benefits of using the zero tolerance at MMC method?

Answer 3

There are three primary benefits of using the zero tolerance at MMC method:
1. Provides flexibility for manufacturing
2. Prevents the rejection of usable parts
3. Reduces manufacturing costs

Question 4

The use of a projected tolerance zone permits the use of the largest position tolerance while eliminating the risk of orientation deviation creating an interference condition.

Question 5

Explain the zero tolerance at MMC method.

Question 6

Explain how a multiple single-segment tolerance is used and specified.

Question 7

In certain cases, the function of a part may require that a hole location allows less deviation in one direction and more deviation in another direction. In these cases, a cylindrical tolerance would not work, and a(n) ____________________ tolerance is used.

Question 8

What is a tolerance analysis chart?

Question 9

A composite position tolerance can only be applied to patterns of features of size.

Question 10

A multiple single-segment position tolerance is often used where the function of a part requires a looser tolerance for the deviations of spacing and orientation of a hole pattern.

Question 11

A(n) ____________________ relationship is where the location deviation of the centerplane of a feature of size is being defined relative to a datum centerplane.

Question 12

A projected tolerance zone is easily verified using a gage pin threaded into the hole. The length of the pin protruding from the hole is ____________________ to the projected height.

Question 13

In certain cases, the function of a part may require a minimum distance of a part to be maintained. The ____________________ modifier is used in a position tolerance when the functional consideration is to tolerance a minimum distance on a part.

Question 14

A(n) ____________________ position tolerance is a feature control frame that contains a single entry of a position tolerance that is applicable to all horizontal segments of the feature control frame.

Question 15

A position tolerance may not be applied to irregular features of size, such as elongated holes.
